I've implemented DNS before. Doing this saves an entire 300 lines of code. At the same time, it makes the DNS server much more complicated. On top of that, implementing a compliant posix libc will now either use a completely different code path, or pull in a huge amount of code to implement HTTP, HTTP/2, and QUIC. If the simpler, cleaner, and more performant route is taken, it willgbreak when someone screws up "legacy" dns without noticing, because it works in the browser. It's not worth the complexity of multiple protocols that do the same thing. And it's not worth making the base system insanely complicated so that the magic 4 letters 'http' can show up. TLS? Yeah, since the simpler secure DNSes failed, we might as well use that. But let's try to keep http complexity contained. |
